Improvement in street-washers



N. PETERS, PHOTO-UTHGHAPHER, WASHINGTON; D. CA

, T0 @ZZ whom it may concern:

Be it known that I, J oHN. MCGLELLAND, of lr the city and county of Washington, in the District of Columbia, have invented certain new and usetul Improvements in Street-Washers; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, makinga part of this specification, in which- Figure l represen ts a vertical section through the case, stop cock, and discharge pipe for street-washer. Fig. 2 shows a top view ot case and lock-plate with closing-cap and the rod for turning the stop-cock. Fig. 3 shows a section horizontally through the three way stop-cock, with the channel in the plug or key for waste water.

My invention consists in the construction r of a pointed or cone-shaped metallic casing, 1n which is firmly secured athree-way hollow cock having an induction-pipe and two outlets in the plug or key,one above the other, to admit the iiow of water to the street-washer, and at the same time not'to out cti' the flow to the 'I house, the plug or key having a channel in it Y to let off' the waste water to prevent freez- /v ing; also projections on the casing and cock to hold it firmly in its place. y

My invention further consists in the application of a closing-cap and lock-plate fitted into the discharge-pipe and the square of the key-rod, so as to prevent the water from being turned on or used by other than those having the key and by the permission of the waterregistrar.

To enable others skilled in the art to make and use my improvements in street-washers, KI will describe them more fully, referring to the drawings, and to the letters marked thereon. 'v The casing A A is made of cast metal, its upper portions varying not materially from the common casing of hydrants, being cast i lin two parts and secured together by screws or bolts.

For the convenience of adjusting the case A A to the right height in setting, and also to prevent the street-washer from bein glifted by freezing so as to break the connection with the pipes, I make the bottom of the case pointat B inFig. l, the

ed or cone-shaped, as seen UNITED STATES PATENT OEEICE,

IMPROVEMENT IN STREET-WASHERS.

Specicai ion forming part of Letters Patent No. 46,572, dated February 28, 1865.

top of the case being enlarged to forni a ledge, a a, on which rests the plate b or support for the eductionpipe C and key-rod D, they both falling below the line of the top of the case sufficient to allow a cap or lid to inclose them under. Onto the top of the discharge-pipe C, and extending over and fitting onto the square d of the keyrod D, is the lock-plate E, for the purpose of holding the stop-cock from being turned in any direction, either when the water is on or turned oft'. This lock may be secured to its place by a cap, F, or other devices, so that when the water is shut oft from thepremises those having the authority to do so can control the letting on at will. On the key-rod D is placed a linger, G, which shows the positions the openings in the plug or key are in relative to the inductionl and the eduction-pipe J and the discharge-pipe C, the cock diftering in this respect from other three-way cocks, in there being two outlets, m and n, the one directly above the other, so that when the plug K is turned to let the water ilow to the pipe J it will also let a iiow into the pipe C,as seen by the arrows in Fig. l. When the plugK is turned one-fourth around in one direction, itv

opens the flow to both of the pipes J and C, and when turned one-half of the way around the pipe C will be closed, but the pipe J will be opened to admit the iiow to the house. Thus it will be seen that a single stop-cock will operate to cut o` the flow of water from one or both of the eduction-pipes or admit the iiow ot' one or both at the same time, the pipes both being stationary, neither of them being I attached to the plug or key K, they being operated the same as a single-way stop-cock.

In the side ofthe plug K, I cut a small channel, i, extending around on the incased part of the plug K, which communicates with the orifice n when the Water is cut off from the street-washer discharge-pipe C, and a small outlet, o, in the cock to let the waste water out of the pipe to prevent freezing. On the sides of the stop-cock H, I make projections h h, in which I form recesses for the nibs r I', made on the inside of the metallic case A A. I also make small lugs p p and q q on the horizontal portion of the stop-cock, to bear against the case A for the purpose of holding the cock H and apparatus firmly in the case when the two castings are secured together,l

Haring thus described my inventiomwhat 1 claim as new, and desire to secure by Letters Patent, is

1. Making the lower end of street-washer cases pointed or coneshaped, inthe manner herein describedfor the purposes set forth.V

2. The three-Way cock K, pipe G, and key D, arranged substantially as described.

3. The small channel '11 in the plug K, connecting with the orifice n and the outlet o, to discharge waste Water, as herein set forth.

4. The lugs p p and q q and the projections h h on the cock K, in combination with the nibs r ^r and the case A, for holding the cock firmly in place. p

5. Embracing the cap F and the rod D of a street-Washer by a sin gle attachment, substantially as described.
